Vulco Viljoen
Senior DevSecOps Engineer
I've spent 15+ years building infrastructure that stays up, stays secure, and stays affordable. My focus now is on the intersection of DevOps and security — pipelines that are hardened by design, observability that surfaces signal instead of noise, and CISSP-track rigour brought to day-to-day engineering.
01 / Experience
Fifteen years, in three chapters
Prior
DevOps Engineer
Built cost-effective, scalable infrastructure on AWS, Azure, and OpenStack. Owned the path from continuous integration to reliable continuous deployment.
Earlier career
Systems & Network Administrator
Cut my teeth on mixed Unix, Linux, and Windows environments — including IBM AIX, WebSphere, and early IBM security tooling (Access Manager, Identity Manager).
My career started building IBM-specific lab environments while working in sales and marketing — which is also where I first learned to love Unix. From there the work shifted through WebSphere administration, then into IBM's security products (Access Manager, Identity Manager), and eventually into the DevOps discipline of treating infrastructure as code.
Log management and analytics has been a constant thread. Getting clustering and load balancing right isn't just an infrastructure problem — for security teams, it's the difference between actionable signal and ignored alerts. That's the lens I bring into DevSecOps work.

Notes from the work
I'm putting together a small archive of field notes — log management patterns, DevSecOps decisions that worked (and some that didn't), and commentary on CISSP material as I work through it.
First posts landing soon.
